Marlene Bonmann

Doctoral Student at Chalmers, Microtechnology and Nanoscience (MC2), Terahertz and Millimetre Wave Laboratory

Marlene is a PhD student at the Terahertz and Millimeter Wave Laboratory (TML) since January 2015. Within TML she is part of the research group that focuses onto graphene based transistors. The aim is to reach the THz regime in order to close the so-called terahertz gap (0.1-10 THz). Exploring this frequency range could lead to new applications for detection or imaging. Marlene’s main task in the graphene group is to examine and understand the interaction between graphene and the materials that are involved in the transistor fabrication process, since these affect graphene’s electrical properties. Understanding the behavior can help to improve the transistor performance by possibly using new materials and new constructional concepts. She studied physics at the Albert Ludwigs University in Freiburg and at Chalmers in Gothenburg.
